ERINTERS BLOCK.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed November 28. 1913. Serial No. 803,563.

To all 'whom it may concern:

Be it known that I, FREDERICK I-l. BnuoLD, a citizen of the UnitedStates, residing at Vyoming, in the county of Hamilton and State ofOhio, have invented certain new and useful improvements in PrintersBlocks, of which the following is a specilication.

My present invention is an improvement upon the printers block shown anddescribed and claimed in my application for patent, Serial No. 665,065,filed December 11, 1911, and has for its object the provision of meanswhereby the printer-s block may be made more readily adjustable.

lt is a further object of my invention to provide a novel extensibleinsert-strip capable of employment in printers blocks of the characterof that described in my aforesaid application, and the invention will befurther readily understood from the following description and claims,and .from the drawing in which latter:

Figure 1 is a plan View of my improved device. Fig. 2 is a side View ofthe same.` Fig. 3 is an end edge view of the same. Fig. l is a verticalcross-section taken on the irregular line 1-1 of Fig. 1. Fig. 5 is avertical longitudinal section taken on the line 5-5 of Fig. 1. Fig. 6 isa front side elevation of the extensible insert-strip shown in partlyextended relation. Fig. 7 is a rear side elevation of the same. Fig. 8is a plan view of the same. Fig. 9 is a bottom view of the same; and,Fig. 10 is a perspective view of the same.

11 and 12 are primary blocks, and 13, 14, are supplemental blocks.Insert-strips 15 are arranged 'to be inserted between the blocks 11 and13 and insert-strips 16 are arranged t0 be inserted between the blocks12 and 14. One or more of these insertstrips may be employed in eachinstance. There is a plate-retaining lip 17 on the supplemental block 13and a plate retaining lip 18 `on the primary block 12.

. A clamping screw 19 is received through a hole 20 in the supplementalblock 13 and into a threaded hole 21 in the primary block 11. Two ofthese'screws are shown. The insert-strips 15 are provided withbottomless recesses 22 for being readily received over the screws, asmore clearly shown in my aforesaid application. The screws clamp theprimary block 11, supplemental block 13 and insert-strips 15 togetherfor forming a main block-section 23.

A screw 25 is received through a hole 26 in the supplemental block 111,similar to the hole 20, and through a threaded hole 27 in the primaryblock 12, similar to the threaded hole 21. The insert-strips 16 zareprovided with bottomless recesses 28, similar to the bottomless recesses22, for being readily received over the screw. The primary block 12,supplemental block 14 and the insertstrips 16 are clamped together bythe screw 25 for forming a main block-section 29.

The main block-sections 23 and 29 are extensible to equal extent byhaving one or more of the insert-strips between the primary blocks andthe supplemental blocks of the respective main block-sections insertedbetween them, and clamping the parts of the respective mainblock-sections together by means of the clamp-screws. The insert-strips15 are preferably of a length equal to the primary block 11 andsupplemental block 13 and the insert-strips 16 are preferably of alength equal to the width of the primary block 12 and supplemental block14. The block-section 29 is preferably auxiliary to the block-section23.

Extension of the printers block in a direction at right angles to theextensions provided for the main block-sections is obtained by means ofextensible insert-strips extensible in length for being adjusted to alength which isequal to the distance between the outer side faces of theprimary block and supplemental block after extension thereof byinsertion of the insert-strip or strips between them. One or more ofthese extensible insert-strips may be employed.

The construction of these extensible insertstrips is such that theirwidth will be maintained when extended in length, so as to maintainproper `distance between all parts of the main block-sections when thesame are in connected relation, Vand means are provided in theextensible insert-strips for permitting the clamping together of themain block-sections irrespective of the extended arrangement of theparts of the extensible insert-strips to lit said main block-sections.

31 is an extensible insert-strip which comprises the members 32, 33. Theouter end portions 34, 35, of these extensible insertstrip members areof equal width and have Shanks 36, 37, extending inwardly therefrom,

these shanks being collectively of a width equal to the width of saidouter end portions, the shanks extending from opposite sides of saidouter end portions when in operative relation between the mainblock-sections.

Shank-receiving rabbets 38, 39, are thus on slides 43 received in slots44 in the pri-l mary block 11 and adjusted by means of adjusting screws45 having' toothed wheels 45 thereon, the said adjusting screws havingthreaded connections with said slides. The adjusting screws are suitablyjournaled in the plate.

The primary block 11 is provided with a rabbet 48. The primary block 12is provided with a rabbet 49 and the outer end portion of the extensibleinsert-strip member 32 is provided with a rabbet 50 for forming acontinuous rabbet for permitting a usual rack-strip to be movedlengthwise thereof throughout the length of the form for operating allof the wheels 46 in line therewith.

The primary block 11 is provided with a rabbet 51, the supplementalblock 13 is provided with a rabbet and each of the insert-strips 15 isprovided with a rabbet 53,

' these rabbets being in line with the wheel 46 extending crosswise ofsaid rabbets, so that the rack-strip may be passed longitudinally of allsaid mating rabbets for clamping` the plates on their several blocks.

One of the insert-strip members, shown as the member 32, is providedwith a recess 55, preferably bottomless for forming a bottomless slot,whereby said insert-strip member is received over a clamping screw 56journaled in a hole 57 in the primary block 12 and threaded into athreaded hole 58 in the primary block 1l. The side walls of the slot 55are received against the screwv for positioning the insert-strip membercontaining said v slot in fixed relation crosswise of the mainblock-sections so that its rabbet 50 may register with the rabbets 4Sand 49. rlhe insertstrip member 33 is provided with anopening 59,preferably bottomless, whereby a narrow end wall 60 is formed at the endof the shank 37; The parts 55, 59, form downwardly opening mouths. Thescrew 56 is received through said opening 59 and through said slot 55,and the parts are so arranged that the insert-strip member 33 may bemoved lengthwise of the insert-strip member 32 for `adjusting theextensible insertstrip 31 to a length equal to the width to which themain block-sections 23 and 29 may have been adjusted. The constructionis such that the wall of the opening 59 adjacent to the end-portion 35and the narrow wall 60 will at all positions of adjustment rest againstthe shank of the insert-strip member 3G fornding support, wherebyeffective. clamping together of the mainblock-sections with theextensible insert-strips between them is effected.

The insert-strips are preferably of the height of the block-sections forsupporting the printers plate, and the extensible insertstrips are ofsuch form that continuous support is obtained for the edges of theprinters plate at the edges of the composite printers block, theintermediate portion of the plate preferably having continuous supportexcept for the slight spaces G1 between adjacent extensible insert-stripmembers and the adjacent plate-supporting faces of the mainblock-sections.

Having thus fully described my invention, what 1 claim as new and desireto secure by Letters Patent, is:
